Specification of Letters Patent.

Patented an. 18,1916.

Application filed November 30, 1914. Serial No. 874,911.

To all whom it may concern:

Be it known that I, I-IANs KARL BITTER,

. a citizen of the Republic of Switzerland, and

resident of Niagara Falls, Province of Ontario, Dominion of Canada, haveinvented following specification and accompanying drawings forming partof the same.

In the drawing, Figure 1 is a sectional elevation of the improved shade.Fig. 2 is .a sectional elevation of a modified form of the same. Fig. 3is a sectional elevation of another form of shade. Fig. 4 is a top view,

partially sectional, of the binding ring and tension bolt shown in Fig.3. Fig. 5 is a vertical section of the binding ring and tension boltshown in Fig. 3. Fig. 6 is a side elevation of a circular lightreflector. Fig. 7 is a side elevation of a V-shaped light deflector.Fig. 8 is a plan view, looklng upwardly, of the shade shown in Fig. 1.Fig. 9 is a plan view, looking upwardly, of the shade shown in Fig. 2.Fig. 10 is a fragmentary perspective of the means for securing theannular strips to the frame. Fig. 11 is a fragmentary perspective viewof a modified form of a deflecting strip mounted on the frame. Fig. 12is a fragmentary perspective View of the frame showing the deflectingstrips mounted thereon.

Like characters of reference refer to like parts in the severaldrawings.

Referring to the drawings, M represents the im roved lamp shadecomprislng the frame Nsuitably hung by the suspending member S andconsisting of a plurality of T-shaped ribs 0 carrying U-shaped bracketsor furrows P cast or cut therein. This frame is designed to support theupper reflector A and lower distributer B thereon, and to facilitate inassembling the several parts, the distributer B is constructed of aplurality of slats of rectangular, S or like section of translucentglass or metal D, each of which engages at its end with the U- shapedbrackets or furrows P in such a manner that between consecutive stripsan air or l1ght space Q, is provided. These strips D are disposed at asuitable predetermined angle to the light source R so that the reflectedlight rays from the upper reflector A or lower distributer B passthrough the spaces Q- which however are so arranged that the lightsource is not Visible. externally. The upper reflector A comprises anannular member of S, corrugated or like section, or a plurality of suchmembers having air spaces therebetween suitably mounted on the frame N.These members are disposed at a suitable angle to the light source R insuch a manner as to facilitate in reflecting the llght rays through thespaces in the refiector and the light spaces Q in the distrptbuter in amanner to be made clear herea er.

It will be understood-that the strips or slats comprisin both thereflector A and the lower distrlbuter B can be made with the outersurface of translucent, white or colored glass, the inner surface of therefiector being matte and the inner surfaceof the distributer highlypolished and mirrored, or if it is found desirable the said strips maybe made of highly polished metal. In assembling the shade it is onlynecessary to engage the ends of theseveral slats D of the distributerwith the U-shaped furrows P of the frame N when the upper reflector Amay be mounted on the said frame.

In Fig. 3 the strips of translucent glass or metal D mounted in theupper portion of the frame N are angularly disposed to those mounted onthe lower portion of the frame and are carried inside a clear glasscontainer F, the lower edge of which is offset and engages with thebinding ring E suitably secured by means of the tension bolt G. .Thereflector A is mounted on a holder H having downwardly disposed airholes I therethrough which are covered by the upper edge of the saidholder'and'dex rored surface of the strips D on the outside of theadjacent strip pass outwardly.

In Fig. 2 the rays of-light on the inside section of the reflector A arethrownfback on the outside of the adjacent concentric section 0 andthence upwardl From this description it wi 1 be seen that the properpath is given to the light to effect an even distribution of the same.

a .What I claim as my invention is:

1. A lamp shade of the class described comprisin a frame, a distributerconsisting of a plura ity of slats mounted on the frame with spacestherebetween and adapted to prevent the light sourc being seenexternally, and an upper reflector consisting of a plurality of annularsections carried by the frame and having spaces therebetween, as and forthe purpose specified.

2. A lamp shade of the class described comprising a frame, a distributerconsisting of a plurality of angularly disposed slats mounted on theframe with spaces therebetween and adapted to lprevent the light sourcebeing seen external and an upper reflector consisting of a'plurality ofangularly disposed annular sections carried by the frame with spacestherebetween, the said reflector and distributer being adapted to causethe light rays to pass through the said spaces.

' 3. A. lamp shade of the class described comprising a frame, adistributer consisting of a plurality of slats of S section'mounted onthe frame with spaces therebetween, and an upper reflector consisting ofa plurality of corrugated annular section shaving spaces therebetween.

4. A lamp shade of the class described comprising a frame, a distributerconsisting of a plurality of slats mounted on the frame and havingspaces therebetween, the, slats I on the upper part of the frame beingangularly disposed to those on the lower part of the frame, and an upperreflector mount: ed on the frame.

5. A lamp shade of the class described comprising -a frame, a lowerdistributer mounted on the frame consisting of a plurality of slats, andan upper reflector mounted on the frame comprising a plurality ofannular sections.

' "6. A lamp shade-of the class described comprising a frame, a lowerdistributer comprlsmg a plurallty of slats mirrored on the mner sidefacing the light source and colored on the outer side and having spacesbetween the consecutive slats, the said slats being adapted to reflectand deflect the light rays through the said spaces.

p A lamp shade of the class described comprising a frame, an upperreflector mounted thereon, a lower distributer. comprising a pluralityof slats of translucent glass having air spaces therebetween, the saidslats bemgadapted to reflect and deflect light rays from the innersurface to impinge .on the-outer surface of the adjacent slats andthence through the spaces, substantially as described. v

8. A lamp shade of the class described comprising a frame, an upperreflector, a lower distributer comprising a plurality of slats havingspaces therebetween, the slats on the upper partof the frame being;angularly disposed to those on the lower part of the frame, and a clearglass contalner surrounding the said distributer.

9. lamp .shadeof the class described comprising a frame, a distributermounted on the frame, an upper reflector comprising a plurality ofannular sections carried by the frame and having spaces therebetween,the

said annular sectlons'being designed to reflect the light rays from theinner surfaces to impinge on the outer surface of the ad-- j acentsection and thence through the spaces, substantially as described.

10. A lamp shade of the clas described comprising a frame inclosing alight source and consisting of a plurality of T-shaped ribs havingU-shaped furrows therein, lower deflecting members mounted on the saidframe comprising a plurality of reflecting sections engaging with the'U-shaped furrows, and an upper reflector mounted on the framecomprising a plurality of annular sec-.

tions, substantially as described.

In witness whereof I have hereunto set my hand in the presence of tWoWitnesses. 1 HANS K. BITTER.
